The understanding I have for CCLM, is that it is a central point that your developers can review the custom code in the environment across the various landscapes and reduce/reuse/recycle code and optimize various systems.
The starting point for CCLM is to download the library from service market place and upload it into your SolMan; not having access to do so will make starting a CCLM project difficult.
